Smart meters are part of a larger effort to upgrade the electrical grid to a state-of-the-art electricity delivery system by using radio frequency technology. Smart meters are similar to wireless Wi-Fi transmitters, like those found at Internet cafes, that allow devices such as laptop computers, tablets and other mobile devices to have wireless access to the Internet. Smart meters also have a digital display, unlike dials found on older meters.
Concerns have been expressed regarding the radio frequency of a smart meter posing a health hazard. We are exposed to many higher powered and continuous sources of radio frequency waves every day in our homes, such as a microwave ovens and Wi-Fi routers. Smart meters use the same FCC-approved radio frequencies that have been used for years in devices such as baby monitors, portable phones, remote controlled toys and medical monitors.
